To all whom it may concern: I

Be it known that I, GEORGE ROBERT NA- eLn, a citizen of the United States, residing at Superior, in the county of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Agitators,

of which the following is a specification.

The present invention relates to improvements in the broad class of agitators, and is particularly applicable to devices for unloading granular material such as coal, ore, etc., from railway cars, docks, and other repositories for this material.

In the handling of granular material such as coal, iron ore and the like from railway cars or docks, difliculty is encountered in the unloading of the same as it is passed from the cars to the docks or from the latter to a second place of discharge, this difficulty being due to the tendency of the material to clog and become packed so that it does not. freely discharge of its own gravity from the cars or from the pockets in the docks.

The primary object of this invention is to provide a device by means of which the ma terial can'be agitated or stirred up, sothat in case of a coal carefrom' which the coal is being dumped, the device is used to agitate loading ore from cars or from dock pockets V in which the ore has been temporarily stored, the latter maybe readily stirred and separated so that it will pass freely to and through the openings or exits provided therefor, and thus dispense with the necessity of shoveling and poking by hand which is now the custom.

@The invention consists essentially in certain novel combinations and arrangements of parts whereby the agitator which is portable may be moved from one point to another for use, and after being located in proper position, means are provided by which the agitator may be operated to agitate or stir up the material in which it is intended to work, and the invention further consists in certain features as will be hereinafter more fully described and claimed.

a In the accompanying. drawings I have illustrated one complete example :of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is a side elevation of an apparatus involving the present invention, wherein a traveler is shown to operate upon a bridge under which railroad cars are located preparatory to dumping. Fig. 2 is an end elevation of Fig. 1, showing a side elevation of one of the railroad cars. Fig. 3 is an enlargeddetail view of the agitator with parts in section. Fig. 3 is a sectional detail view of the guide plate used in conjunction with the movable agitator bar. Fig. 4 is a plan view of the transporting and oscillating devices for the agitator bar. Fig. 5 is a vertical sectional view of Fig. 4.

In the preferred embodiment of my invention, I have illustrated a portable bridge 1 supported upon the upright end frames 2-2 which are mounted upon suitable wheels 3 whereby the entire bridge may be moved longitudinally the tracks in any desired manner or may be left stationary if preferred.

The bridge and frame-work which are constructed of suitable material and in proper manner are designed to support a traveler which I have indicated as a whole by the numeral 4 in Fig. 1. This traveler or carriage is supported upon wheels 5 that are adapted to run on tracks 6 shown in Fig. 2, and the tracks are supported upon the floor of the bridge 1. This traveler or carriage is adapted to travel from end to end of the bridge 1 so that the agitator indicated as a whole bythe numeral 45 may be moved from one point to another so that it can be used in connection with any of the four lines of cars indicated by the numeral 8 in Figs. 1 and 2, which arrangement of cars is that usually found upon ore docks now in common use. To accomplish the movement of the traveler I provide an endlesscable or rope 9 which is attached at one end 10 to one end of the bridgel and at theother end of the bridge at point 11, and this cable 9 is given a one and one-half turn about the ring or annulus 12 upon the traveler ,4. There are two guide sheaves 13 and l twhich are suitably supported from the floor 16 of the traveler, to guide the cable as it leaves and enters the ring 12. The

" of asprocket '38 and suitable chain 39 leadring 12 is adapted to revolve horizontally upon the floor 16 of the traveler and surthrust of the rim 12 when the traveler isin motion. Small rollers 19' may be installed,

within the floor 16 to form a suitable verticial bearin'g for the rim 12 and a keeper band 20 may surround the lower projecting base of the rim 12 to hold the latter in position and keep dust and grit from entering the Wearing parts of'the rim '12 and various rollers. However, it is'understood that other forms ofsupport for the rim 12 may beemployed without departing from invention.

'An 'annular rack 21 is formed upon the uppermost face of the r1m 12 and; which engages a gear wheel 22' mounted upon the shaft 23jjournaled within a second annular rim or ring "2 1 which latter is designed" to revolve upon the tracks '25 on the upper Wall of'the and for which purpose it is mounte d upon desired number, of suit- 7 able rollers 26, 1 thus} permitting of the rim 1 24; being' revolubly' operative independent of ,therims 12 and17', by means of the vertica'l shaft 27' revolubly mounted in any con- --i:-."' t vement manner upon the r m 24; andoperatlng a spur gear 28 which meshes with the j annular raelr29 formed upon the innermost wall the rim 17 whereby the rim' 24L may be made. to revolve uponfthe track 25 as is evident,"motion being imparted to the upper end of the shaft .27 from the operating power, within the motor cage f T he motor cage is supported from the rim 24; and travels with it so thatthe operator fhas a: clear view of his work at all times.

Power may be transmitted" in any convenient manner from the motorcage to the radially disposed shaft 23 whereby the gear p22 hi'h engages therael; 21 ma bemade to revolve at will which when the rim 2 1 is: held" against revolution will permit of the it r'm2t bei 'g revolved, the object of. which Will appe r er Diametrieally, pivotally mounted Within bearings 31 integral with the rim 24 is a frame comprising the meinbers'32-333 1 and 35 one end of Which-frame is mounted upon a stub shaft 36' and the opposite end 1 199 an; ngated. a tf 7; h f f e olublyfoperatedfrom its outer end by means from the motorcage and having upon 765' rigidly fixed to the arson-sleeve 42 rev its innermost'eriid the beveled gear which meshes with 'andldrives the beveled gear 4 1 olubly mounted within the bearings 13 and 14 within the members 33 and 35 of the pivotal frame.

The agitator stem 15 is preferably square in cross section and is mounted Within the elongated sleeve -12 in such a manner as to admit of reciprocal motion therein but con fined to the revolving motion of the sleeve 42. The entreme ends of the agitator stem 45 are'supp'orted by the cross head 46 at the top and the cross head 17 at the bottom, these latter being" united by two brace rods 1 348 upon either side of the stem, extending the full length thereof and slidably pa ssthroug'h'themembers 32 of the pivotal frame, in such a manner as to permitof the entire agitator and its attachments being readily *raised or lowered. To accomplish this raising and lowering of the agitator and also toproduce an oscillating'motion of same when desired, I provide the stay lines %9 and 50 attached to either end of the cross head 17 and leading through to sheaves 51 and 52 mounted upon'the' rim 2 1 to any suitable meehanism, not shown, within the motor cage, and arranged in such a manner as to beoperate'd in either direction simultaneously, or individually, thus permitting of the'agitator being moved up or'down or swung to any angle desired, as is evident, it be ing mounted within the pivotally suspended frame and therim carrying the frame being susceptible to revolving motion and this en;

tirely independent of any desired revolving motion of the agitator.

The cross head'l'l is provided with a thimble'53 which has a square opening through itseenter for the reception of the stem #415, and is formed 'externally'with an annular groove 54 which engages the edgesof the opening in the cro'ss'head 47 so that the thimble will revolve with the stem within the brass head.

An externally screw threaded bit 55 is illustrated in the drawing as being removably'attachable to the extreme lower end of the stem 45 and forms the agitator proper, for disengaging the lodged ore or coal within the receptacle over which the device may be working, and it" is evident that many otherforms of agitatingbit 'or brush might be made use of.

In *the operation of the apparatus the traveler is brought to the desired position Withrelation to the bridge 1 by operating the revolving rim"12j until the traveler is broughtdirectly over the car which is being unloadedl The agitator bar 4-.5 is now rotated through the described mechanism and is lowered into'the oar inposition to stir up or agitate the coal in the car. By means ofthe cables 19 and 50 the vertical position of the agitator baris determined, and may als e sei at d 1 9 it p v l p o to any desiredangle. In this manner'move ments may be imparted to the agitator bar as follows: First, the traveler may be caused to travel from right to left in Fig. 1 over the car, the agitator bar may be raised, lowered and oscillated by means of the cables 49 and 50 and pivotal support. Thus providing wide range of adjustment of the bar and insuring its reaching to any and all points of the car that is being unloaded, so that the contents may be continually stirred up or agitated and prevented from clogging, and made to pass freely through the discharge opening in the bottom of the car.

It will be understood that the agitator bar is applicable for use in dock pockets and other similar receptacles, and it is applicable for use in many other different ways not herein illustrated. Its utilization provides for great saving in labor and time, and obviates one of the objectional features of hammering on the side of the metallic railway car to dislodge the clogged material inside the car.

Having thus fully described my invention, what I claim as new and desire to se cure by Letters Patent, is I l. The combination with a traveler, of a rotary ring having rollers, a supporting bracket on the traveler for said rollers, rack teeth on the ring, and a rack wheel engaging said teeth, means for rotating said rack wheel, and a cable having both its ends anchored and frictionally engaging and passed around said rotary ring.
